各种各样的中枢神经系统损害与心率(HR)的变化有关。然而，在癫痫患者中，它们对偏侧化癫痫发作的价值仍然存在争议。本研究旨在评估与部分发作相关的心率变化是否有助于癫痫发作的定侧。我们分析了38名连续接受视频-脑电遥测监测的患者(平均年龄：27.5岁)100例癫痫发作的心率变化。在发作前30秒、发作后10秒、20秒和120秒分别测定R-R间期。我们评估心率变化是否与每次发作的发作类型、左右差异和不同的符号成分有关。分析中排除了3例非偏侧发作；63/97例(65%)起病于左侧大脑半球，主要发生在颞叶(57.7%)。平均基线心率为每分钟77次(HR：大于或等于每分钟107.06次)，其中23/32例发作性发作于内侧颞叶结构，16/32例发生在发作后10秒内，16/32例发生在发作后20秒内，与发作点无关。在每次发作的不同符号成分中，只有肌张力障碍姿势和自动与HR增量相关。我们在我们的系列中没有发现心动过缓。发作性心动过速最常见的是源于内侧颞叶的癫痫发作，它可能不能可靠地预测癫痫发作的偏侧化。(C)2001东亚银行贸易有限公司。
A wide variety of CNS lesions have been associated with changes in heart rate (HR). However, in epileptic patients their value to lateralize seizure onset remains controversial. This study aims to assess if HR changes associated with partial onset seizures could be useful in lateralizing seizure onset.We analysed HR changes on 100 seizures from 38 consecutive patients (mean age: 27.5 years) admitted for video-EEG telemetry monitoring. We evaluated the R-R interval 30 seconds before the seizure onset and 10, 20 and 120 seconds after the onset. We assessed whether there was a correlation between HR changes and seizure type, left/right differences and different semiological components for each seizure.We recorded 100 seizures. Three non-lateralized seizures were excluded from the analysis; 63/97 (65%) had left hemisphere onset, mainly from the temporal lobe (57.7%). The mean baseline HR was 77 beats per minute Ictal tachycardia (HR: greater than or equal to 107.06 beats per minute) was detected in 32 seizures, with ictal onset from the mesial temporal lobe structures in 23/32; 16/32 occurred during the first 10 seconds and 16/32 during the next 20 seconds from the seizure onset independently of the site of origin. Among the different semiological components for each seizure, only dystonic posturing and automatism correlated with HR increments. We did not find bradycardia in our series.Ictal tachycardia occurs most frequently with seizures arising from the mesial temporal lobe and it may not reliably predict the lateralization of seizure onset.
